AUTOMOBILE HEATER.

Application filed September 18, 192%. Serial No. 738,5e i.

My invention relates to automobile heaters that utilize the exhaust gas and is simple .in-

construction and is placed in front of the seat and rests upon the floor. Owing to the sim- 5 plicity of its construction it is thoroughly heated and yet avoids burning the clething ortheparts oithe car near it. ti-an be easily installed andasieasily' removed front-the car and receives the cold air from the floor and This 1. accomplish 1 discharges it from above.

by the means hereinafter fully do ed and as more particularly pointed out in. the claims.

in the drawings Figure 1 is a heater.

Figure 2 is a longitudinal vertical section.

Figure 3 is a top plan of the heater with a portion of the outer casing broken away.

Figure 4 is a transverse vertical section at the entrance end of the passageways on line 4 Figure 2. v

Figureo is a similar section on line 5 5, Figure 2.

Reference will now be made to the accompanying drawings-that form a part of this specification in whichthe similar parts ofthe structure are marked throughout the figures by corresponding reference characters. I In the drawings, represents casing that has sheet metal end pieoes'll, the lower portions of which are bent outwardly to provide lateral flanges 12, which have bolt-holes therein, through which the bolts 13 pass and secure the same to the floor. The upper edges of said end pieces 11 are. rounded and flanged inwardly, and they are connected by a longitudinally extending sheet metal shell 14:, whose upper and outer portions are perforated. The lower edges of this shell terminate above the lower edges of the head 11, sufiiciently to leave side spaces .70 through which the cooler atmosphere passes into the heater.

This casing rests upon and is secured to a metal floor-plate 15, at each end, by bolts 13 that pass through bolt-holes in said plate, which latter corresponds in length and width to the casing.

At one end of plate 15 a longitudinally extending opening 16 is made, the edges. of which correspond in contour to a cross section of the Siamese outlet and inlet stubs 17 and 18 respectively. These stubsextend vertically and are cast in one piece with a longitudinally extending" hollow radiator casting having passageways 19 and '20. These pasfront view of my llllPlOVQCl sageways extend from near one end of the casting to the other and are separated by a horizontal wall 21 whicharises from the transverse partition between stubs 17 and 18 ,to about the center of the casting, and then extends centrally and longitudinally thereof to near the opposite end of the casting, where it terminates and leaves the opening 22 in the end thereof that connects the inlet and-outlet passageways; This radiator or heater cast ing is of ,the same transverse dimensions throughout its length and is provided with a series of exterior transverse fins 23,v which, preferably, are of the same dimensions and continue throughout the length of the casting. The surface of the interior walls of the passageways 19 and 20 may be also provided with a series of surrounding transverse fins 24 that, preferably, correspond in dimensions and extend throughout the length thereof, and said fins 2 1 do not close the bores of said current ofhot gas passing therethrough to be hit thereby and pitched from side to side in transit.

ill

The central portion of the floor-plate is slightly raised and the radiator casting is directly secured thereto by screws 25.

I prefer to increase the transverse dimensions of the casting where the stubs 17 and 18 enter the same and to flatten the surface thereof opposing the floor-plate, and a packing sheet 26 01 asbestos is placed between the two parts.

The inlet-stub 17 is connected in a suit-able manner to the dischargepipe of the engine,

and the exhaust-stub 18 is connected with the discharge-pipe o1 theautomobile. The course and construction of the exhaust-pipe of the .r

engine and the discharge-pipe of the automo bile are well understood and have not, therefore, been particularly described herein. The flow of heated gases thoroughly heat the walls ofthe radiator casting, and the air entering the casingunder the side edges of the latter becomes thoroughly heated by the radiator and the exterior fins thereof, and after becoming heated it escapes from the casing through apertures in the shell 14 at a higher plane than that at which the air enters said.

casing.

It will be noticed that my improved heater can be very easily kept clean, particularly when dirt and dust settle upon the floor-plate. All that it is necessary to do is to push a flat brush in and under the raised lower edges of the sides of the shell 1a and brush the top of said floor-plate clean. lhe vibration of the car will dislodge any dust from the radiator onto the floor-plate, and thus, in the manner just indicated, the heater can be kept clean. The ends, being iinperforated, prevent dirt lodging where it could not be readily reached with a brush or the like.

hat I claim is 1. An automobile heater comprising a suitable casing, a longitudinally extending hollow asting therein having parallel upper and lower walls and having an inlet passageway and parallel outlet passageway extending intothe lower wall, an inlet stub connected to said inlet passageway at one end of said casting, an outlet stub connected to said outlet passageway alongside said inlet stub, a transverse wall separating said inlet and outlet passageways and 7 extending from between said stubs to the oppositeportion of said casting, and terminating back of the end wall to provide communication between the passageways, and a series of fins projecting inwardly from the walls into said passageways and inclined in the direction of the flow of gas through said passageways whereby to cause an undulating flow of gas.

2. An automobile heater comprising a casing consisting of sheet-metal concavo-convex ends and a perforated shell connecting said ends and supported thereby whereby to space the casing from the floor, a longitudinally extending radiator enclosed within said casing having inlet and outlet passageways extending therethrough, stubs connected to the respective passageways and passing through the floor ol' the automobile, and a plate to which underneath portions of the radiator are secured, said plate having a slightly raised portion whereby to provide an insulating air space above the floor. 7
